EXTOXNET PIP - ALLETHRIN
... 5620 ppm for d-allethrin in mallards and bobwhite quail [19]. Effects on aquatic organisms: The pyrethroid insecticides, including allethrin, are toxic to fish. Fish sensitivity to ... in laboratory degradation studies, pyrethroid concentrations decrease rapidly due to sorption to sediment, suspended particles and plants. Microbial and photodegradation also occur [19]. Breakdown in vegetation: No ...

EXTOXNET PIP - AZINOPHOS-METHYL
... Several studies have indicated that azinphos-methyl causes adverse effects in wildlife. Wild mammals and aquatic organisms appear to be more vulnerable than birds to hazards created by this material [29 ... other metabolites. Azinphos-methyl has a low to medium tendency to adsorb to sediments or suspended solids [12]. Breakdown in vegetation: Residue levels of azinphos-methyl in crops are dependent on ...

EXTOXNET PIP - BACILLUS THURINGIENSIS
... not reveal any population changes after aerial spraying of B.t. formulation [148]. Effects on aquatic organisms: B.t. is practically nontoxic to fish [150]. Rainbow trout and bluegills exposed for ... for up to 48 hours in water. Afterwards, it gradually settles out or adheres to suspended organic matter [150]. Breakdown in vegetation: B.t. is relatively short-lived on foliage because ...

EXTOXNET PIP - CARBOFURAN
... water, carbofuran is subject to degradation by chemical hydrolysis under alkaline conditions. Photodegradation and aquatic microbes may also contribute to degradation. The hydrolysis half-lives of carbofuran in ... respectively. Carbofuran does not volatilize from water, nor does it adsorb to sediment or suspended particles [14]. Breakdown in vegetation: The half-life of carbofuran on crops is about ...

EXTOXNET PIP - CHLOROBENZILATE
... different species of fish [9,17]. Chlorobenzilate is not expected to bioconcentrate in aquatic organisms [12]. Effects on other organisms: Chlorobenzilate is nontoxic to beneficial insects, including honeybees ... volatilize from soil surfaces [12,32]. Breakdown in water: Chlorobenzilate adsorbs to sediment and suspended particulate material in water. It is practically insoluble in water [17]. It is ...

EXTOXNET PIP - DIMETHOATE
... do, which may account for its relatively higher toxicity in these species [26]. Effects on aquatic organisms: Dimethoate is moderately toxic to fish, with reported LC50 values of 6.2 mg ... in water: In water, dimethoate is not expected to adsorb to sediments or suspended particles, nor to bioaccumulate in aquatic organisms [12]. It is subject to significant hydrolysis, especially in alkaline waters ...

EXTOXNET PIP - DINOCAP
... ]. Ducks fed 50 ppm of this fungicide in their food developed cataracts [32]. Effects on aquatic organisms: Dinocap is very highly toxic to fish; the reported 96-hour LC50 values for ... slightly soluble in water, and if found in water will most likely be adsorbed to suspended colloidal materials or precipitated in sediment. Breakdown in vegetation: Dinocap is readily absorbed and translocated ...

EXTOXNET PIP - DIQUAT DIBROMIDE
... quail [36]. Effects on aquatic organisms: Diquat dibromide is moderately to practically nontoxic to fish and aquatic invertebrates. The 8-hour LC50 ... in the water are similar to those normally present during aquatic vegetation control programs [93]. There is little or no ... to open water, it disappears rapidly because it binds to suspended particles in the water [95]. Diquat dibromide's half-life ...

Effects on aquatic organisms: EDB is slightly toxic to fish [8]. The reported LC50 value ... is 40.3 mg/L. The calculated bioconcentration factor for EDB in aquatic organisms ranges between 9.3 to 10.2, suggesting that it ...

EXTOXNET PIP - ETHION
... in the environment and may be stored in plant and animal tissues [62]. Effects on aquatic organisms: Ethion is very highly toxic to freshwater and marine fish, and to freshwater invertebrates ... is almost insoluble in water [13]. In open waters, it is likely to adsorb to suspended particles and bottom sediments. The persistence half-life of ethion varied from 4 to 22 ...
